KAC looks with field-fast fitting

The Pirate Arms KAC QD 175mm Silencer replicates the iconic Knight’s Armament quick-detach can. At 175mm it stands slightly longer than the 145mm version in the same family, giving your AEG or gas blowback build a serious, purposeful profile that makes the opposition think twice about stepping into your lane.

On and off in seconds

The quick-detach design is the whole point. Fit the supplied-style M4 birdcage muzzle to your rifle once, and from then on the suppressor slips on and off over the top with no tools required in the field. Perfect for switching between a compact CQB setup and a longer field configuration.

Built light, built tough

Machined from anodised aluminium at roughly 250g and 38mm diameter, it adds presence without unbalancing the front end. The 14mm CCW thread interface matches the vast majority of M4-pattern airsoft replicas.

Choose your finish

Available in Black or Tan so you can match an existing rifle or two-tone build. The hollow body also gives you room to house a tracer unit or barrel extension. Explore more airsoft accessories to finish the look.

Frequently asked questions

How does the quick-detach system work?

You fit a compatible M4 birdcage-style flash hider to your rifle first, then the KAC suppressor slips over the top and locks on. No tools are needed in the field to take it on and off.

What thread does it use?

It is built for the airsoft-standard 14mm CCW (counter-clockwise) thread found on most AEG and gas blowback M4-pattern replicas.

Do I need any tools?

Not for the suppressor itself. You may need a tool to remove your existing flash hider when installing the required birdcage muzzle, but after that the can is tool-free.

How long is it compared to the 145mm version?

At 175mm it is noticeably longer than the Pirate Arms 145mm can in the same design, giving a more aggressive silhouette and extra hop-up cover on longer builds.

Does it change how my gun shoots?

It is a cosmetic and balance accessory. It will not upgrade FPS or range, but it adds presence, protects the muzzle and can house a tracer or extension inside the hollow body.
